School strengthening:slab, beam strengthening with fiber reinforced polymer composite

The compressive strength of concrete is not satisfied with the design requirements; reinforcement is used to reinforce the bonded carbon fiber reinfroced polymer(CFRP) composite strengthening

School strengthening:slab, beam strengthening


Project overview

The school dormitory building a top layer of concrete beam and slab design strength of concrete C30, by using the rebound method and the compressive strength of concrete beams and plates on the spot detection and evaluation of core drilling method, a layer of beam and plate are age concrete batch intensity estimation value is 20.3MPa, can not meet the requirements of design, reinforcement of the beam structure.


School canteen is the top layer of concrete beam and slab design strength of concrete C30, by using the rebound method and the compressive strength of concrete beams and plates on the spot detection and evaluation of core drilling method, a layer of beam and plate are age concrete batch intensity estimation value is 20.1MPa, can not meet the requirements of design, reinforcement of the beam structure.
